Abstract
Hemodialysis leukopenia was studied using various dialyzers and membranes. We found that dialyzers with cellulosic membranes caused marked leukopenia, but in recently developed non cellulosic membranes, its occurrence was significantly less. Additionally, our results showed a newly developed cellulose acetate membrane to correlate well with the non cellulose membranes regarding leukopenia, in spite of it being a derivative of cellulose. The extent of white blood cell decrease seemed to correlate inversely with an increase in the ultrafiltration rate per membrane area of dialyzer. The relationship between leukopenia and hypoxemia was examined also. The results of this investigation are included, however, we feel that more research is necessary before any conclusions can be made.
